By the means of thermodynamic and statistic mechanics analysis , the relationship between the all species in plasma generator and reactor and their partition functions was obtained in the local equilibrium at constant temperature and pressure. The change of the distribution of all hydrogen species (states) with temperature in generator and reactor was achieved by calculating partition function, respectively. These provide a reference for further investigation.
